3.1 FUNCTION PRINCIPLE

3.1.1 REMOTE MONITORING UNIT

TV/TA converts strong voltage and current into 5A/1A and 100V alternating waveforms is converted into suitable small signals for computer sampling by high accurate convertor, which are sent to A/D after filtering and become digital signal, finally enter into CUP for calculation The device collect 128 points for each cycle wave to get A/D sampling for CT, PT and DC transmitter, and calculate the AC monitoring value of current, voltage, active power, reactive power, active kwh, reactive kwh, power factor, frequency and etc according to discrete expression of N times equal interval sampling

AC collection input and output are as follows:

Input: Ua, Ub, Uc, U0, Ux, Ia, Ib, Ic, 3I0

Calculate: Ua, Ub, Uc, Uab, Ubc, Uca, U0, Ia, Ib, Ic, I0, P, Q, CosΦ, f, ±kwh, ±kvarh, 31 times harmonic component。

DC collection input are 0-5V, 1-5V signals, output after converting are as follows:

DC1, DC2, DC3, DC4, DC5, DC6。

AC sampling principle is equal interval sampling for a continuous waveform; according to the sampling theorem the sampling points of a sine wave can describe the characters of the sine wave completely Actually voltage and current cannot be pure sine wave and it must include higher harmonics Thus more sampling points more accurate, however, for the limit of hardware actual condition, it is impossible to add sampling points infinitely, so our device choose sampling

of 128 points

As each cycle doing N points sampling, frequency tracking calculation is necessary, or sampling as per 50Hz cycle will arise error because power frequency is unequal to 50Hz The device do frequency tracking calculation and equal interval sampling after adjust sampling period

Remote monitoring includes two-meter method and three-meter method and the monitoring method is shown in the figure:

For two-meter method monitoring, voltage input are Ua, Ub, Uc, while calculation amount adopted are Uab and Ucd, and current input are Ia,Ic The calculation formula is as follow:

3.1.3 REMOTE COMMUNICATION UNIT

Remote communication is introduced by null node, converted into digital signal after photoelectric isolation and then enters into device to acquire status signal and deflection signal For the filter circuit within the collection of remote communication data, the scanning time of the CUP to remote communication is 0.3125ms to guarantee its resolution less than 1ms, and record start as deflection begin, thus the signal collection can prevent the contact chatter In addition, each signal collection has filed-setting limit to make sure the accuracy of signal function After device confirm the status deflection, the first deflection record time is regarded as the remote communication deflection time Its time sequence is shown as figure:

3.1.4 REMOTE CONTROL UNIT

Control operation is ordered by dispatching or local monitoring, and control unit is mainly responsible for the reception and return to check the order, then according to the correct order to output corresponding control information, i.e., output the order for switch tripping or closing Each remote control output is controlled by CPU, and the operation steps include: select, return

to check and execute, which achieve the output checking of relay, guarantee the safe and available executing of remote control Moreover, the device has hardware self-checking latching function which can prevent error output for hardware damage

3.1.5 INTEGRAL ENERGY FUNCTION

Basic calculation of kwh:

Active kwh calculation formula:

Reactive kwh calculation formula:

Where wh0 and VARh0 are the initial value of active and reactive kwh, the accumulative value of the energy before this period, and ΔWh and ΔVARh are the energy increment during this period

Calculate once per minute, then:

Where K is the time interval to calculate kwh, K=60/n, n is the times of calculation per minute, e.g if n=1200, i.e., calculate 20 times per second and K=0.05 Pi is the average of P in every time interval, i.e., average in 0.05s, ΔWh and is the active kwh increment of 1 minute

3.1.6 SYNCHRONIZATION FUNCITON

According to settings closing operation can be no check, synchronization check and no-voltage check, and synchronization check only or no-voltage check only, however, here only explain the operation process of synchronization check closing

3.1.6.1 ENTER THE SYNCHRONIZATION CHECK CLOSING PROGRAM

In local method, receive the closing order from management SCM, or in remote method, receive closing order from upper computer, then set corresponding KK as 1(KK is one of EEPROM), after receive confirmed signal, enter to operate closing program

3.1.6.2 NO CHECK CLOSING OPERATION

If configuration no check, the unit will close directly without assessing the differential condition of voltage and frequency after receive the closing order from upper computer or unit

3.1.6.3 NO-VOLTAGE CHECK CLOSING OPERATION

If monitoring configuration is no-voltage check closing, after enter into the closing program, device send out closing order instantly and closing the breaker when line voltage Ux<Uwyzd

（Uwyzd is no-voltage check setting value）or bus voltage Um, Um<Uwyzd

3.1.6.4 SYNCHRONIZATION CHECK CLOSING

If configuration is synchronization check closing, and voltage of both sides are higher than low-voltage blocking value, synchronization check closing operation will be done as the follow steps:

1) Voltage difference check: if there is voltage on both side, find out voltage difference If Ux

is from A,B line voltage(Ux is from analogy of Ubc/Uca), ΔU＝Uab–Ux If Ux is from A phase voltage(Ux is from analogy of Ub/Uc), ΔU＝Ua–Ux If ΔU ≤Utc (Utc is voltage difference setting value), it is regarded as qualified If ΔU Utc, and it still cannot meet the requirement during the return time of synchronization, that means communication cannot meet the synchronization condition and have to exit the operation procedure of closing 2) Frequency difference check: if voltage difference is qualified, find out frequency difference

Δf ＝f1–f2, if Δf ≤ftc(ftc is frequency difference setting value), it is qualified and will go

to phase difference check If Δf ftc, and it cannot meet the requirement during the return time of synchronization, that means communication cannot meet the synchronization

condition and have to exit the operation procedure of closing

3) Synchronization check closing: go for synchronization check after both voltage and frequency difference qualified Compare the time difference of square wave rising edge between bus voltage and line synchronization voltage to find out phase difference, calculating once per cycle(about 20ms),and the calculate formula is Tm is bus voltage cycle, while Δt is the time difference of square wave rising edge of both side voltage, and the both unit is ms, so Φc=0.36°fm·Δt。When phase difference is changed from

1800 to 1600 , calculate the closing ahead angle Φt, and the calculate formula is Φt=

×360°=0.36·Δf·tht (Tc is slip dispatch period, is ahead time of synchronization)

4) Calculate the variable quantity of phase difference for each period: calculate phase difference Φc each period after find out Φt To make sure complete the synchronization check closing in a slip dispatch period and that the phase difference of both side voltage close to 0 as closing, predicting closing time is adopted, and the concrete operation is as follow: calculate the variable quantity ΔΦc of a period (the time when calculate the two phase difference)phase difference Φc by slip dispatch period Tc and bus voltage period

Tm, and the formula is :

should deduct the procedure operation time from frequency sampling to figure out tyc Stop closing operation and communicate to exit synchronization information if it yet cannot meet the synchronization condition during synchronization return time Monitoring frequency and voltage difference should be together with phase difference check, and it should be exit and communicate exiting reason if frequency or voltage difference changes to unsatisfied the condition

7) When enter into synchronization check, if ΔUvoltage difference setting value,

Δffrequency difference setting value, Φc≤20 and no less than 20 times distinguish in 1s all satisfy the condition, it is regarded as loop network power supply and instant closing is available

Note: for this device the synchronization function is fixed on remote control 1 closing

3.1.7 ANALOG CALIBRATION

For the hardware in the device, all the components in each channel are fixed parameter Thus the disparity of channel component parameter (current, voltage convertor, resistance in filter circuit, capacitance etc.) cause amplitude and phase error of each channel AC collection coming from the AC sampling data after fourier-transform To make sure the accuracy of sampling, software calibration for A/D channel is necessary The principle is: the amplitude of AC coming from the AC sampling data after fourier-transform multiply a calibration coefficient Kx, and add a calibration angle φx in phase angle to eliminate the effect to AC signals because of different channel component parameter The A/D channel calibration is the process to figure out calibration coefficient Kx of channel amplitude and phase calibration angle φx The channel calibration for this device includes manual and automatic, and the first one is to input channel calibration coefficient and angle by MMI

Attentions: Channel calibration is very important and only input the gradeⅡpassword of user can the main microcontroller enter into channel calibration To avoid big error of sampling value because of too large AC signal or damage of some channel component, which may cause abnormal of calibration value Kxi and φxi, the amplitude calibration coefficient is limited in 0.850～1.150, and phase calibration angle φxi is limited in ±8.00°

1) Accuracy automatic modulation

Accuracy automatic modulation is used in device maintenance, which is to add a rated value in each channel and input an equal value to exterior from clavier, then press ―OK‖, herein this coefficient is read-in EEPROM The accuracy automatic modulation also includes phase modulation (Debug at factory, user does not do it)

2) Accuracy manual modulation

It is the extension for the first function When manual modulation is needed, add a rated value in channel and calculate the coefficient between rated value and displayed value to read-in EEPROM, finally modulate the accuracy
